Oral oestrogens appear not to be effective for reducing recurrent urinary tract infections
compared to placebo in postmenopausal women.
A Cochrane review «»1 «Perrotta C, Aznar M, Mejia R, Albert X, Ng CW. Oes...»1 included 4 studies with a total of 2798 women. Oral oestrogens did not reduce UTI
compared to placebo (RR 1.08, 95% CI 0.88 to 1.33, 4 trials, n=2798). Adverse events
were breast tenderness, vaginal bleeding or spotting.
Comment: The quality of evidence is downgraded by study quality (unclear allocation concealment).
